Abstract
A device designed to interconnect with an inflatable thermia blanket. The device conveys a medium into the blanket, which applies an internal pressure to the device, and has at least two temperature settings for controlling the temperature of the medium and a pressure sensing apparatus. The pressure sensing apparatus measures the internal pressure. And when the measurement exceeds a predetermined level of internal pressure then any one of the at least two temperature settings is useable. Otherwise, when the measurement does not exceed the predetermined level of internal pressure, the device will either convey the medium at a predetermined temperature setting, which can include shutting the device down.
